To aZZ whom it may concern.-

"Be it known that I, GEORGE F. BROTT, a citizen of the United States, residing in the city of WVashington, District of Columbia, have invented certain new and useful Improvements in Methods of Making Shoes; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to to which it appertains to make and use the same. My invention is an improvement in the method or process of making boots or shoes. The object of the invention is to secure the sole to boots or shoes having soles and I 5 uppers of leather or material of like consistency without the use of pegs or thread, and to render the same water-proof by the insertion of a sheet or lamina of prepared rubber fabric or similar material between the inner and outer soles, which sheet of fabric also assists in the cementing and prevents the stripping of the cemented parts.

A shoe made according to my process is illustrated in the accompanying drawing,in 2 5 which the figure represents a vertical longitudinal section thereof.

A is the upper, and B the insole, to the un der surface of which the upper is cemented.

O is the sheet or lamina of prepared rub- 0 ber fabric, cemented to the under side of the insole and over the edges of the upper, and D is the outsole, which is cemented to the under side of the rubber sheet 0.

It has been proposed heretofore to make 3 5 shoes without sewing or pegging by bringing the ends of the uppers down over the edges of the insole, cementing the same thereto, filling up the space made by the folds of the upper on the bottom of the insole, and cementing the outsole to the insole and upper. By the practice of this process the cement is left exposed to dampness, which affects its adhesiveness, and, being applied to adjacent hard surfaces, is subjected in use to great strains from the tendency of the parts to slip on each other upon bending the sole, and for these and other reasons the fastening has not been found durable.

I have discovered by experiment that rubber and leather may be cemented together much more securely than two pieces of leather, or other comparatively inelastic substances can be cemented to each other, and it is the utilization of this discovery upon which one of the main points of my invention is based. The sheet of rubber fabric I use forms an elastic yielding filling between the two soles, to which the cement readily adheres, and this prevents the cracking, stripping, or breaking of the cement and the stripping of the ce- 6o mented parts when it is placed between two hard surfaces, and by the use of which and the pressure which is applied air is expelled and bubbles in the cement are prevented, which would aifect the adhesiveness of the cement. It also serves to keep water or dampness from soaking through to the foot. By reason of the use of this waterproof dam between the soles a hard paper or composition insole is entirely satisfactory, thus reducing 7c the cost of the material for the shoe.

My process therefore consists in lasting the upper and cementing the edges of the same to the under side of the insole, cementing a sheet of prepared rubber fabric to the 7; under side of the insole and over the edges 'of the upper, cementing the outsole to the rubber fabric on the under side of the insoles and upper, and applying pressure to secure the full adhesiveness of the cement.

In carrying out my process or method I prefer to use a single sheet of leather for the outsole, to which the heel may be secured in a manner similar to that above described or by nails; or I may use an integral sole and heel made of composition material resembling leather. WVhen this is done, the shoe is complete when the outsole has been cemented to the insole.

Having now described my invention, what I claim is The improved method of making shoes having soles and uppers of leather or material of like consistency, herein described, which consists in lasting the upper and 0e menting the edges of the same to the under In testimony whereof I affix my signature in the presence of two Witnesses.
